BMW Radiator Shutter Assembly - Genuine BMW 51745A22C65

Product Information

The radiator shutter assembly, also known as an active grille shutter, is an airflow management component located at the front of the vehicle. It opens and closes electronically controlled louvers to regulate air entering the radiator and engine bay. By optimizing aerodynamics and engine temperature, the shutter assembly improves fuel efficiency, reduces emissions, and helps the engine reach operating temperature more quickly. Constructed from durable plastic and equipped with an electric actuator, it is engineered for continuous operation in varying driving conditions.

• Check engine light or fault codes related to airflow control – caused by a stuck or malfunctioning shutter actuator.
• Overheating or poor engine warm-up – due to shutters not opening or closing properly.
• Reduced fuel efficiency or increased wind noise – from shutters stuck in the open position.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
